| 摘 要： | 针对日益严重的电力系统谐波污染问题,文章介绍了一种新型的嵌入式谐波检测装置的设计。该装置采用主从结构,以单片机为主CPU控制整个装置的运行,以DSP为从CPU进行数据处理,并采用一种新型的谐波检测算法——卡尔曼算法,以最小均方误差为准则,根据前一个观测数据和最近的一个观测数据,利用状态方程和递推方法估计当前过程状态,可实时、可靠地检测电网中的谐波,具有运算速度快、精度高、结构简单、造价相对低廉、操作简便、显示功能强等特点。仿真结果证明了该装置的有效性和可靠性。

| Abstract: | Aiming at increasingly serious problem of harmonic pollution in power system,the paper introduced design of a new type of embedded harmonic detection device.The device adopts master-slave structure,which takes single-chip microcomputer as main CPU to control running of the whole device and takes DSP as slave CPU to process data,and adopts a new type of harmonic detection algorithm named kalman algorithm,which takes the minimum mean square error as rule and uses state equation and recurrence method to estima... |
